echo "<tr>\n";
foreach ($row as $item)

$quantity = oci_fetch_array($qty_parse, OCI_ASSOC);
echo '/'.$quantity.'<meter value=10 min="2" max="10"></meter>';
}else {
echo ' ';
}
}

Answer 1

Looks like oci_fetch_array() returns array (array in function name should tell you something ;)).
You can use var_dump($quantity); to see what was returned by this function.
I guess that what you need to do is something like this: echo '/'.$quantity['qty'].'<meter value=10 min="2" max="10"></meter>';

Answer 2

First of all, your $row variable is not defined. You can use next solution:
$qty_parse = oci_parse($conn, 'select qty from master_drawing');
oci_execute($qty_parse);
while ($item = oci_fetch_array($qty_parse, OCI_ASSOC))
{
echo " <td>".($item['qty']);
if (is_numeric($item['qty'])){
echo '/'.$item['qty'].'<meter value=10 min="2" max="10"></meter>';
}else {
echo ' ';
}
}
P.S. When oci getting associated array via OCI_ASSOC - your script gets $item variable like:
$item['qty'] = 'value';
If you want to get value from $item as string variable, redefine you variable on loop like:
$item = current($item);
